We're dividing 21318016 by 432 
We want to figure out the number of times 21318016 can be divided by 432.

On to step 1:
432 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 432

Let's proceed to step 2:
If we divide 21 by 432, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 432

Step 3:
432 can be fit into 213 0 times, resulting in a remainder of 213.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 213, we get 213.
Bring next digit (1) of the dividend behind the 213 and repeat the process: 2131 / 432

Step 4:
If we divide 2131 by 432, we get 4 and a remainder of 403.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 403 after subtracting 1728 from 2131.
Bring next digit (8) of the dividend behind the 403 and repeat the process: 4038 / 432

On to step 5:
When dividing 4038 by 432, we get 9 with a remainder of 150.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtract 3888 from 4038 to get 150.
Include the next digit (0) from the dividend after 150, then repeat: 1500 / 432

Let's proceed to step 6:
432 goes into 1500 3 times with a remainder of 204.
The next digit of our result is 3. 
Result so far: 493.0
If we take 1296 away from 1500, we end up with 204.
Fetch the next digit (1) from the dividend, attach it to 204 and continue: 2041 / 432

Going ahead to step 7:
432 can be fit into 2041 4 times, resulting in a remainder of 313.
Use 4 as the next digit of our solution. 
Result so far: 4934.0
If we subtract 1728 from 2041, we get 313.
Take the next digit (6) from the dividend and append it to 313, then repeat: 3136 / 432

On to step 8:
432 goes into 3136 7 times with a remainder of 112.
The number 7 becomes the next digit in our result. 
Result so far: 49347.0
If we subtract 3024 from 3136, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 9:
432 can be fit into 1120 2 times, resulting in a remainder of 256.
Write down 2 as next digit of the result. 
Result so far: 49347.2
Subtract 864 from 1120 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 10:
The number 432 fits into 2560 5 times, leaving a remainder of 400.
Put 5 as the next digit of the answer. 
Result so far: 49347.25
Subtracting 2160 from 2560 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 11:
If we divide 4000 by 432, we get 9 and a remainder of 112.
Write down 9 as next digit of the result. 
Result so far: 49347.259
If we take 3888 away from 4000, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 12:
When dividing 1120 by 432, we get 2 with a remainder of 256.
Use 2 as the next digit of our solution. 
Result so far: 49347.2592
Subtract 864 from 1120 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 13:
If we divide 2560 by 432, we get 5 and a remainder of 400.
Use 5 as the next digit of our solution. 
Result so far: 49347.25925
If we take 2160 away from 2560, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 14:
4000 divided by 432 is 9 with a remainder of 112.
Use 9 as the next digit of our solution. 
Result so far: 49347.259259
Subtract 3888 from 4000 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 15:
1120 divided by 432 is 2 with a remainder of 256.
Write down 2 as next digit of the result. 
Result so far: 49347.2592592
Subtracting 864 from 1120 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 16:
432 can be fit into 2560 5 times, resulting in a remainder of 400.
Record the quotient 5 as the next digit in the result. 
Result so far: 49347.25925925
If we take 2160 away from 2560, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 49347.25925925, and the remainder is 4e-07.
